This is a very strange assertion. What is your definition of "system"?
X? okay... Restart X.
Console access? I don't see how apps can do that. CTRL-ALT-F1 is
recognized in the kernel. Apps can trigger bugs in the kernel, but if the
console is locked up the kernel had to participate in the failure.
Some versions of Netscape used to trigger a denial-of-service (DOS) on my
cpu resource (sucked it up in an infinite loop), but if I was
patient my keystrokes would be responded to and I could kill the
offending process. To manage my impatience, I used ulimit to restrict the
maximum number of cpu-seconds netscape could use, until I upgraded
it.
